Kenya Introduces Phased Income Tax Filing from January 2027

The Finance Act 2026 has introduced a phased approach to income tax filing that will take effect from January 2027. All taxpayers will no longer file returns by the single June 30 deadline that has applied for years.

Individuals chargeable to tax must now submit their returns by the last day of the fourth month after the end of their year of income. For those on a calendar year basis this means filing by April 30.

Every person other than an individual, such as companies and other corporate entities, must file by the last day of the sixth month following the end of their accounting period. This keeps their deadline at June 30.

The change amends Section 52B of the Income Tax Act. It responds to recurring system congestion at the Kenya Revenue Authority during peak filing periods.

National Treasury Cabinet Secretary John Mbadi explained the rationale during parliamentary discussions. He noted that spreading filings across months gives KRA staff more time to verify accuracy instead of rushing through large volumes at once.

Pre-populated returns, which begin in January 2026, support the shorter window for individuals. Data on incomes and expenses is already captured, reducing the burden on taxpayers who previously rushed to meet the June deadline.

Kenya Revenue Authority has faced system challenges in recent years. In the financial year ended June 2025 the authority extended the filing deadline to July 5 because of technical hitches that affected many users.

The phased system aligns Kenya with practices in other jurisdictions such as South Africa. Officials expect it to improve the quality of returns submitted and reduce last-minute pressures on both taxpayers and the authority.

Corporate taxpayers, which include many construction and infrastructure firms, retain the June 30 deadline. This category covers companies involved in projects ranging from roads and housing to commercial developments.

PAYE taxpayers form the largest group contributing to income tax revenue. They will now operate under the April 30 deadline for individuals, giving them a clearer four-month window after the year ends.

The Kenya Revenue Authority will have more opportunity to cross-check filings before final assessments. This should reduce errors and disputes that often arise when large volumes arrive close together.

Taxpayers will receive clearer guidance on their specific deadlines based on whether they are natural persons or corporate entities. The shift aims to make compliance more manageable without changing tax rates or liabilities.

Implementation will begin with returns for the year of income ended December 31 2025. Individuals will file between January and April 2027 while corporates follow their usual timeline up to June.

The National Treasury and Kenya Revenue Authority are expected to issue detailed guidelines ahead of the rollout. These will clarify how pre-populated data interacts with the new deadlines.

Businesses in sectors such as construction will need to adjust their internal accounting cycles to align with the June deadline for corporate filings. Proper planning will help avoid penalties for late submission.

Overall the reform seeks to modernise tax administration. By spreading the workload it reduces the risk of system overload and allows better focus on verification and enforcement where needed.
